Description

0402CS-R12XJRW is a surface‑mount current‑sense resistor in the 0402 package. It’s designed to drop a small voltage to sense current in power circuits.
Key points:
- Size: 0402 (about 1.0 × 0.5 mm).
- Value: nominal 0.12 Ω (R12).
- Series: CS – Current Sense resistor family.
- Suffix: XJRW encodes tolerance, temperature coefficient and termination finish per the manufacturer (exact specs vary by vendor; consult the datasheet).
- Power rating and TCR: vendor‑specific; typically a few tens of milliwatts with a defined TCR and RoHS/lead‑free finish.
Typical use:
- Place in series with a load to monitor current in DC‑DC converters, motor drivers, battery management, etc.
- Measure V = I × 0.12 Ω; design PCB traces to minimize stray inductance.
Note:
- For exact tolerance, TCR, termination, and power rating, refer to the specific manufacturer’s datasheet for 0402CS-R12XJRW.

Package

It's an SMD chip resistor in the 0402 package (size 1.0 × 0.5 mm).

Pinout

Two pins. Function: a 0402 size current-sense (low-value) resistor, value 0.12 Ω (R12), used to measure current.

Application

0402CS-R12XJRW is a 0402-size chip resistor (12 Ω, J tolerance). Common uses include pull-ups/pull-downs, current limiting, voltage dividers, RC filters, and impedance matching in compact SMT circuits. Suitable for mobile/handheld devices, wearables, automotive electronics, consumer electronics, telecom, industrial control, medical devices, and other high-density power-management and signal-conditioning applications.

Equivalent

I need more details to give accurate equivalents. 0402CS-R12XJRW could be a 0402-size shunt resistor (R12 = 0.12 Ω) or another 0402 component, and cross-references vary by manufacturer. Please specify:
- component type (resistor, capacitor, PTC, etc.)
- original manufacturer
- target suppliers (Mouser, DigiKey, RS, etc.)
- power rating and temperature coefficient if known.
With that, I can provide precise cross-references.
