Cemented and enamelled wiredound resistors model SFD

The resistors of the SFD series are low-power resistor, the main characteristics for this resistors are the compactness and the small dimensions that permit to use this products on electronic printed boards. The terminal may be tinned and permit a fast insert on electric board.

Nominal resistances series E 12 (10%), Series E 24 (5%),
DIN41426
Climatic category (IEC 68) 55/255/10
Solderability (260 °C x10s.) ≤ 1% + 0,1 Ω
Temperature cycling (-55°C / +200°C) ≤ 2% + 0,1 Ω
Damp heat (21 days 40 °C / 95% r.h.) ≤ 3% + 0,1 Ω
Resistance rangeTs = 250°C 1,000 h : -1.0 till +3.0%
10,000 h : -1.5 till +5.0%
100,000 h : -2.0 till +8.0%

The mentioned values apply for 99,7% of all resistors.
For low value-resistors, the mentioned variations may be exceeded by 0,1 Ω.
Reliability : At 70 °C, ambient temperature,25% r.h. and 250°C surface temperature standard rating for complete failure : <= 100 x 10-9/h.
