Comparison with Similar Models

FAQs

1. What is the maximum voltage for RC0402DR-07137KL?

50V DC or AC (RMS) as specified in YAGEO's datasheet. Exceeding this may cause arcing or degradation.

2. Can it be used in automotive underhood applications?

Yes, but ensure operating temperatures stay within -55°C to +155°C range and consider additional conformal coating for humidity protection.

3. How does its stability compare to thin film resistors?

Thick film resistors typically show higher TCR (100ppm/°C vs. 25-50ppm/°C) but offer better cost-efficiency for many applications.

4. What's the recommended soldering profile?

Follow IPC/JEDEC J-STD-020 guidelines for Pb-free reflow: peak temp 260°C for ≤10 seconds.

5. Is RoHS compliance guaranteed?

Yes, YAGEO confirms compliance with Directive 2011/65/EU and amendments.

Future Trends

Emerging requirements will likely drive:

• Higher precision (≤±0.25%) in compact packages

• Lower TCR materials for automotive/industrial use

• Increased integration with embedded passives
