LTR18 is ROHM's 1 / 2W high power chip resistor with high welding strength, high surge voltage and high power tolerance.
The LTR18 is a high‑power chip resistor with a wide‑terminal design that improves solder welding strength and surge resistance. It is intended for automotive, industrial, and power‑supply applications and complies with ISO‑9001 and ISO/TS16949 standards.
The datasheet lists electrical ratings such as a rated power of 0.5 W (1/2 W), a maximum rated voltage of 200 V, and an operating temperature range from –55 °C to +155 °C. It also details resistance tolerance codes (D 0.5 %, F 1 %, J 5 %) and temperature coefficients, as well as packaging options like paper‑tape reels (5 000 pcs per 180 mm reel).
