Higher voltage ratings for 800V EV architectures.
Integration of embedded temperature sensors.
Smaller packages (e.g., 0805) with equivalent performance.
Q1: Is the TNPV1210121KDEEA RoHS compliant?
A: Yes, it complies with RoHS Directive 2015/863/EU.
Q2: Can it be used in RF circuits?
A: While possible, thin film resistors are less ideal for RF than thick film due to higher parasitic inductance.
Q3: What's the shelf life?
A: 5 years when stored at <40°C/60% RH per IEC 60068-1.
Q4: How does it compare to wirewound resistors?
A: Thin film offers better high-frequency response but lower power handling than wirewound.
Q5: Is reflow soldering recommended?
A: Yes, per IPC/JEDEC J-STD-020 profile with peak temp ≤260°C.
