LTR Series High Power Chip Resistors (Wide Terminal Type) LTR10 / LTR18 / LTR50

Overview

The unique wide terminal structure is robust against mechanical stress at the junction induced by board expansion/contraction. This, combined with original laser trimming design and resistive element construction, ensures high surge resistance characteristics and greater rated power.

(Units: mm)

Part No.	Size	L	W	t
LTR10	2012	1.2	2.0	0.35
LTR18	3216	1.6	3.2	0.5
LTR50	5025	2.5	5.0	0.9

Features

Superior temperature cycling resistance
3kV ESD resistance
The entire lineup is available in D (±0.5%), F (±1%), and J (±5%) tolerances.
Operating temperature range: -55ºC to +155ºC
Higher rated power enables smaller resisters to be used
