Metal Alloy Low-Resistance Resistor
● LR Series |  | |
|---|---|---|
■ Construction |
 |
|
| ■ Application — Power supply — Battery pack — DIY tools — Inverter/Converter (AC/DC, DC/DC, DC/AC) — Measurable instrument — Consumer electronics — Note book — PC power pack — LED driver — Others (Auto tronics… etc.) |
|---|
| ■ Features — Ideal for all types of current sensing, voltage division and pulse applications including switching and linear power supplies, instruments, power amplifiers. — Very low inductance 0.5nH to 5nH. — Stable high frequency characteristic with reduced lead inductance and excellent frequency response. — Low thermal EMF (<1μV/°C). — Pure tin plating provides compatibility with lead (Pb) free and lead containing soldering processes. — Excellent stability (|ΔR/R| ≤ ± 0.5% for 1000h at 100°C) different environmental conditions. |
