1 / 1 page RCD type LF2 is designed to provide circuit protection for telecom applications, such as line feed, ADSL, HDSL, and switching networks, as well as snubber circuits, switching regulators, power faults, etc. The LF2 is a combination power resistor and isolated thermal fuse housed in a ceramic case. The combination enables the device to withstand short-time overloads (various lightning surges, AC power crosses, inrush currents, and ESD pulses), yet open safely under extended overload conditions. The all-welded internal construction combined with highest grade materials ensures utmost performance and reliability. For even greater protection under power cross conditions, as required by TR1089, specify LF2A. Industry’s widest range! Withstands lightning surges and power crosses Resistance range: 0.01 Ω to 10KΩ LF2 1 Ω to 1.6K meets UL497A, Bellcore GR1089, ITU-T K.20 LF2A meets Bellcore TR1089 specifications Standard tolerance: ±1% or ±5% (available to ±0.01%) Available on RCD’s exclusive SWIFT TM delivery program! FEATURES FAILSAFE FUSIBLE WIREWOUND RESISTORS TYPICAL PERFORMANCE CHARACTERISTICS LF2 SERIES * LF2A resistance range is 1.8 Ω to 100Ω OPTIONS Option A: TR1089 performance Option X: Non-inductive (0.2µH max ≤50Ω, 0.37µH >50Ω) Option ER: 100 Hour Burn-In Customized fusing characteristics Matched pairs or groups Failsafe surge resistors are often tailored to particular customer requirements. Consultation with RCD’s Engineering department is recommended on all applications to ensure optimum performance at the most cost-effective price. Depending on the application, Series LF2 or LF2A can often satisfy the requirements of UL497A, UL1950, UL1459, FCC Part 68, REA 397 & PE60, Bellcore GR1089 & TR1089, ITU-T K.20 & K.21, VDE 0750, IEC 1000-4, CCITT K17, IEEE 472 &587, ANSI C37.90 & C62.41, SAE J1113, MIL-STD-704, MIL-STD-1399, & MIL-STD-1275. HOW TO USE LF2 Pin #1 and #2 shall be shorted together by the user on the PCB. The LF2 resistor is connected into the circuit via pins #3 and #4. 1 2 3 4 A E D | C | B F 1 2 3 4 .032” Pin 1 & 4, .023” Pin 2 & 3 → ↓ → ← ↑ ↓ ← ↑ ← → APPLICATION NOTES: D C R e p y T e g a t t a W C ° 5 2 @ e c n a t s i s e R e g n a R ] m m [ h c n I S N O I S N E M I D AB C D E F 2 F LW 0 . 21 0 . 0 Ω K 0 1 - ∗ Ω 2 0 . ± 5 4 0 . 1 ] 5 . ± 5 . 6 2 [ 2 0 . ± 0 5 4 . ] 5 . ± 3 4 . 1 1 [ 2 0 . ± 5 6 2 . ] 5 . ± 3 7 . 6 [ . n i M 5 2 1 . ] 5 . ± 7 1 . 3 [ 5 1 0 . ± 0 0 7 . ] 4 . ± 8 7 . 7 1 [ 5 1 0 . ± 0 0 9 . ] 4 . ± 6 8 . 2 2 [ g n i t a r e D e g a t t a WC ° 5 2 > C ° / W m 1 2 ) s r u o h 0 0 0 1 ( e f i L d a o L% 5 . 0 ± e c n a t s i s e R e r u t s i o M% 1 ± g n il c y C e r u t a r e p m e T) C ° 0 2 1 + o t 5 5 - ( % 5 . 0 ± d a o l r e v O e m i T t r o h S) c e S 5 , W 0 1 ( % 2 . 0 ± y t il i b a p a C e g r u S g n i n t h g i L 6 . 5 2 F L Ω K 0 1 - 0 0 1 - 8 . 1 A 2 F L Ω 0 1 , k a e p A 0 0 1 / V K 1 S µ 0 0 0 1 x S µ 0 1 Ω k a e p ( p e r S 0 6 x s e s l u p 0 5 , e c r u o s ) . l i a v a V K 0 1 o t p u s e g a t l o v t n e i c i f f e o C e r u t a r e p m e T 0 1 .
