ORDERING INFORMATION - GLOBAL PART NUMBER

Part number is identified by the series name, size, tolerance, packaging

type, temperature coefficient, taping reel and resistance value.

SCOPE

This specification describes

AC0402 to AC2512 chip resistors

with lead-free terminations made by

thick film process.

APPLICATIONS



All general purpose applications



Car electronics, industrial

application



Superior resistance against

sulfur containing atmosphere



MSL class: MSL 1



AC series soldering is

compliant with J-STD-020D



Halogen free epoxy



RoHS compliant

-

Products with lead-free

terminations meet RoHS

requirements

-

Pb-glass contained in electrodes,

resistor element and glass are

exempted by RoHS



Reduce environmentally

hazardous waste



High component and equipment

reliability



The resistors are 100% performed

by automatic optical inspection

prior to taping.

The ordering code for an AC0402

chip resistor, value 100 KX with

±1% tolerance, supplied in 7-inch

tape reel is: AC0402FR-07100KL.

NOTE

1. All our RSMD products are RoHS

compliant and Halogen free. "LFP" of the

internal 2D reel label states "Lead-Free

Process".

2. On customized label, "LFP" or specific

symbol can be printed.

3. AC series with

±0.5% tolerance is also

available. For further information, please

contact sales.

(3) PACKAGING TYPE

R = Paper/PE taping reel

K = Embossed taping reel

(4) TEMPERATURE COEFFICIENT OF RESISTANCE

(5) TAPING REEL

07 = 7 inch dia. Reel

10 = 10 inch dia. Reel

13 = 13 inch dia. Reel

7D = 7 inch dia. Reel with double quantity

(6) RESISTANCE VALUE

1Ω to 10 MΩ

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”.
