CRCW08059M76FKEAC

FAQFrequently Asked Questions

• Can CRCW08059M76FKEAC be used as a very high-value bias or pull resistor in precision analog circuits? Yes. CRCW08059M76FKEAC from Vishay Dale is a 9.76 MOhm, 1% thick film resistor, so it is commonly used for high-impedance biasing, leakage sensing, timing networks, and feedback paths where loading must stay low. In precision nodes, the main design checks are input leakage, PCB contamination, humidity effects, and the resistor’s ±100 ppm/°C drift, since those can become comparable to the intended current at megaohm levels.
• Is CRCW08059M76FKEAC suitable for capacitor discharge, RC timing, or long time-constant circuits? CRCW08059M76FKEAC can be used in RC networks where a 9.76 MOhm value is needed, including delay, hold, and discharge paths. At this resistance level, capacitor leakage, board surface leakage, and temperature effects often influence the actual timing more than the resistor tolerance itself, so layout cleanliness and dielectric choice should be reviewed along with the nominal RC calculation.
• What should I check before replacing another 0805 9.76 MOhm resistor with CRCW08059M76FKEAC? CRCW08059M76FKEAC is an 0805 thick film resistor with 1% tolerance and 1/8W rating, so a drop-in replacement depends on matching package size, resistance, power dissipation, and voltage stress. For replacement work, verify that the original part allows an 0805 footprint, that the circuit current will not overheat the resistor, and that any required tempco, pulse handling, or high-voltage behavior is compatible with thick film construction.
• Can CRCW08059M76FKEAC be used in industrial environments with wide temperature swings? CRCW08059M76FKEAC is specified for -55°C to 155°C, which supports many industrial temperature ranges. In long-term use, the practical checks are self-heating, board-level contamination, and drift over time, especially if the resistor sits in a high-impedance sensing path where small leakage currents can affect the measured value.
• Is CRCW08059M76FKEAC a good choice for high-voltage divider networks? CRCW08059M76FKEAC is often used in divider strings because its 9.76 MOhm value reduces current draw. The main design question is not only power, but also voltage across the resistor and the resistor’s physical spacing within the layout; for high-voltage dividers, confirm the circuit’s per-resistor voltage stress, creepage distance, and any surge or transient exposure before committing to CRCW08059M76FKEAC.
• What are the practical differences between CRCW08059M76FKEAC and the substitute RC0805FR-079M76L? CRCW08059M76FKEAC and RC0805FR-079M76L are both 0805, 9.76 MOhm, 1% style replacements, but substitution still needs a footprint and performance check. The practical comparison points are tolerance class, tempco, power rating, packaging, and supplier qualification, because even when the nominal value matches, the assembly line or end application may depend on specific thermal or reliability characteristics.
• When would CRCW08059M76FKEAC not be the best choice for a design? CRCW08059M76FKEAC may be a weaker fit when the circuit sees high pulse energy, continuous high voltage, or requires very low leakage error in a humid or contaminated environment. In those cases, engineers often evaluate higher-voltage resistor families, different compositions, or larger packages to reduce stress, because an 0805 thick film part can be limited by geometry and surface effects even when the average power looks acceptable.
• Can CRCW08059M76FKEAC be used in sensitive ADC input networks without affecting accuracy? CRCW08059M76FKEAC can be used in ADC input conditioning when a very high resistance is needed, but the system-level accuracy depends on source impedance, sampling capacitor charge time, and leakage current on the PCB and MCU input pin. With a 9.76 MOhm resistor, the interface usually needs validation against acquisition timing and board cleanliness, since the resistor value alone does not determine the effective input behavior.
• Is CRCW08059M76FKEAC appropriate for battery-powered products where standby current matters? CRCW08059M76FKEAC is often a practical fit for battery-powered designs because 9.76 MOhm limits DC current to a very small level. The trade-off is that high-value nodes are more sensitive to contamination, humidity, and parasitic leakage, so the layout, solder mask quality, and cleaning process matter more than they would with lower-value resistors.
• How does CRCW08059M76FKEAC compare with 9C08052A9764FKHFT for design-in decisions? CRCW08059M76FKEAC and 9C08052A9764FKHFT can both serve as 9.76 MOhm 0805 options, but the right choice depends on the exact dielectric, pulse handling, reliability data, and vendor qualification requirements. For a redesign or second-source strategy, CRCW08059M76FKEAC should be checked against the alternate part’s temperature coefficient, voltage rating, and any application-specific restrictions before treating them as interchangeable.
• What assembly or storage conditions matter for CRCW08059M76FKEAC in production? CRCW08059M76FKEAC is supplied in tape and reel and has MSL 1, so it is straightforward to handle in standard SMT workflows and does not impose special moisture-bake handling under normal conditions. In production, the key controls are solder profile, placement accuracy for the 0805 body, and maintaining clean PCB surfaces around very high-resistance nodes to avoid leakage after reflow.
• Is CRCW08059M76FKEAC a reasonable choice for long-life instrumentation or control equipment? CRCW08059M76FKEAC can fit long-life equipment when the circuit needs a stable 9.76 MOhm resistor in a compact 0805 footprint. For long service life, engineers usually review drift mechanisms, environmental contamination, operating temperature excursions, and whether the resistor will see sustained electrical stress near the top of its dissipation or voltage envelope.
