TT electronics' metal alloy chip resistors
Providing design engineers with robust resistive devices capable of withstanding large surge currents, TT electronics IRC offers two series of low resistance metal alloy current sense chip resistors. Designated the ULR and LRMA Series, the resistors feature a metal strip construction capable of withstanding high temperatures and large currents.
“TThe ULR and LRMA Series resistors are ideal for use in current sense circuits in power electronics and automotive systems.
The RoHS compliant and halogen free ULR and LRMA Series resistors feature low TCRs (50, 75, and 100ppm/°C) and inductance values. Resistance ranges from 0.5mΩ to 100mΩ, with power ratings from 1W to 3W, depending on device. The ULR Series resistors are offered in 1206, 2010 and 2512 chip sizes, while the LRMA Series devices are available in 0815, 1206 and 2512 chip packages.
