GLOBAL PART NUMBER
SR XXXX X X X XX XXXX L (1) (2) (3) (4) (5) (6) (7)

(1) SIZE: 0201 / 0402 / 0603 / 0805 / 1206 / 1210 / 1218 / 2010 / 2512
(2) TOLERANCE: D = ± 0.5% F = ± 1% J = ± 5% K = ± 10% M = ± 20%
(3) PACKAGING TYPE: R = Paper taping reel K = Embossed taping reel
(4) TEMPERATURE COEFFICIENT OF RESISTANCE:

– = Based on spec.


(5) TAPING REEL & POWER:

07 = 7 inch dia. Reel & Standard power

7W = 7 inch dia. Reel & 2 x standard power

13 = 13 inch dia. Reel

7T = 7 inch dia. Reel & 3 x standard power

47 = 7 inch dia. Reel & 4xstandard power

 

(6) RESISTANCE VALUE

1 Ω ≤ R ≤ 1M Ω There are 2~4 digits indicated the resistance value. Letter R/K/M is decimal point, no need to mention the last zero after R/K/M, e.g.1K2, not 1K20. Detailed coding rules of resistance are shown in the table of “Resistance rule of global part number”.

 

Resistance coding rule Example

XRXX (1 to 9.76 Ω) 1R = 1 Ω 1R5 = 1.5 Ω 9R76 = 9.76 Ω

XXRX (10 to 97.6 Ω) 10R = 10 Ω 97R6 = 97.6 Ω

XXXR (100 to 976 Ω) 100R = 100 Ω

XKXX (1 to 9.76 KΩ) 1K = 1,000 Ω 9K76 = 9760 Ω

XXKX (10 to 97.6 KΩ) 10K = 10,000 Ω 97K6= 97,600 Ω

XXXK (100 KΩ) 100K = 100,000 Ω


CONSTRUCTION

The resistor is constructed on top of a high-grade ceramic body. Internal metal electrodes are added at each end and connected by a resistive glaze. The resistive glaze is covered by a lead-free glass. The composition of the glaze is adjusted to give the approximately required resistance value. The whole element is covered by a protective overcoat. The top of overcoat is marked with the resistance value. Finally, the two external terminations (Ni/matte tin) are added,
