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

ꢀ 0.0025Ω to .25Ω, 0.5% to 10%

RCD Type (LOR3, LOR5, or LV3)

Options: E, 4T, 18 (leave blank if standard)

Resis. Code (see table above):

0.5% & 1%: 3 signif. digits & multiplier; R010=0.01Ω, R150=0.15Ω

2%-10%: use 2 signif.digits & multiplier; R01=.01Ω, R10=.1Ω, etc.

Use extra digits as needed R005, R0025, R0075, R012, etc.

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 ~1mΩ/in., 0.04” dia. have ~0.6mΩ/in).

An extra inch of .032” leadwire in the circuit will increase the TC of a 10mΩ

resistor by roughly 350ppm. Keep leadwires short for best TC stability.

Tolerance Code: D=0.5%, F=1%, G=2%, H=3%, J=5%, K=10%

Packaging: B = bulk (std.),T = Tape & Reel (not avail. on option 4T)

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.

Termination: W= Lead-free, Q= Tin/Lead (leave blank if either is acceptable,

in which case RCD will select based on lowest price and quickest delivery)
