What is TPAN0263F1R00K9 used for?

The datasheet identifies applications including current sensing, energy absorption and discharge, RC snubbers, high-speed switching, voltage regulation, constant-power loads, industrial equipment, and motor-control circuits.

What should engineers review before using TPAN0263F1R00K9?

Review the thermal path from the bottom flange into the PCB or heatsink. The 50 W rating is specified only with the flange held at or below 25 °C; without a heatsink, the rating is 2.25 W.

What are the key specifications of TPAN0263F1R00K9?

Key specifications are 1 Ω resistance, ±1% tolerance, ±100 ppm/°C TCR, 500 V maximum working voltage, -55 °C to +150 °C operating temperature, 2.5 °C/W thermal resistance, and ≤0.1 µH inductance.

What is the pinout of TPAN0263F1R00K9?

Use the TPAN0263F1R00K9 datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about TPAN0263F1R00K9 pinout to locate pins, power rails, and interface signals before layout.

AI summary

A 1 Ω, ±1% TO-263 thick-film power resistor for high-power current sensing and energy dissipation where the thermal flange is properly cooled.

Best for

High-power current sensing
RC snubber and energy-dissipation circuits
Thermally managed industrial and motor-control designs

Avoid if

No heatsink or thermal PCB area is available
Required dissipation exceeds 2.25 W without controlled cooling
A verified lifecycle or supply commitment is required

Check before use

Confirm flange temperature remains ≤25 °C at the intended 50 W load.
Validate solder voiding and thermal interface performance.
Check voltage and pulse conditions against the application waveform.
