1 / 1 page LOR Series LOR rectangular shape and high thermal conductivity ceramic case efficiently transfers heat from the internal element resulting in excellent stability and overload capability. Series LV3 molded design offers improved uniformity for high-volume auto- placement applications. The resistance element of LOR and LV3 is non-inductive and constructed from near-zero TCR alloy minimizing thermal instability. Construction is flame retardent, solvent- and moisture-resistant. Ideal for current sense applications 0.0025 Ω to .25Ω, 0.5% to 10% Low TC, high pulse capability Non-inductive metal element Available on RCD’s exclusive SWIFTTM delivery program! Choice of 2-terminal or 4-terminal designs OPTIONS Opt.18: .040” lead dia. on LOR3 (.040” is std on LOR5) Option 4T: 4 Terminal Option E: Low thermal emf design Non-std resistance values, custom marking, burn-in, etc. PRECISION LOW-OHM METAL PLATE RESISTORS APPLICATION NOTES: 1) 3W parts to be measured at 1.31” [33.3mm], 5W parts at 1.67” [42.4mm]. Also available per customer requirement. 2) 18AWG (0.040” dia) leads are standard on LOR5 and available on LOR3 (specify opt. 18). RCD recommends .040” leads, since the heavier gauge results in lower lead resistance, improved heat transfer, and lower in-circuit TCR (.032” leadwires have resistivity of ~1m Ω/in., 0.04” dia. have ~0.6mΩ/in). An extra inch of .032” leadwire in the circuit will increase the TC of a 10m Ω resistor by roughly 350ppm. Keep leadwires short for best TC stability. 3) To achieve utmost precision in current sense or shunt applications, RCD offers LOR3 & LOR5 in 4-terminal version, specify opt.4T (eliminates lead resistance when utilized in Kelvin configuration). Request App. note #R31 for performance comparison of 2- vs. 4-terminal. , 25 50 75 100 125 150 175 200 225 250 275 100 75 50 25 0 Temperature °C TEMPERATURE COEFFICIENT (typ.)
