CRH2512F5K10E04Z 2512 5.1KΩ ±1% Tolerance 2W High-Power Thick Film Chip Resistor
CRH2512F5K10E04Z follows Ever Ohms' CRH high-power coding:
-
CRH – High-power thick film series, "up-rated wattage in same footprint"
-
2512 – Imperial 2512 (6.4×3.2mm, metric 6432)
-
F – Tolerance ±1% (precision grade; J=±5%, G=±2%)
-
5K10 – Nominal resistance 5.1KΩ
-
E04Z – 2W power rating + ±100ppm/°C TCR, Pb-free tape & reel
Core spec: 2512, 5.1K, ±1%, 2W.
Standard 2512 thick film parts cap at 1W; CRH pushes to 2W@70℃ via thicker film paste, widened side terminals, and alumina ceramic substrate (power density ~doubled). For this 2512 5.1K 2W part:
-
Rated 2W, max working voltage 200V, short-pulse capable
-
±1% tolerance (F-grade), TCR ±100ppm/°C, -55~+155℃
-
Anti-sulfuration coating, NiPdAu terminations, SMT-friendly
-
RoHS / REACH compliant, partial AEC-Q200 baseline for automotive periphery
5.1K sits in the "mid-high" band — not a current-sense value, not a weak pull-up. The 2512 5.1K 2W fits divider / sampling / feedback circuits:
-
SMPS & fast-charger adapters: secondary feedback divider, primary start-up dummy load
-
BMS & energy storage: pack voltage sensing divider (±1% helps multi-cell accuracy)
-
Industrial: PLC analog input divider, sensor bridge bias, inverter aux loops
-
LED drivers / automotive lighting: constant-current feedback arms
-
Appliances: HV detection divider on main control boards
Against a standard 2512 5.1K 1W part, CRH gives 2× power headroom — single-device solution, no parallel 1206 needed. Against J-grade (±5%), the F-grade ±1% trims system error in feedback/sense paths, while BOM cost stays well below alloy or thin-film alternatives.
Ever Ohms (Taiwan) has 30+ years in passive manufacturing; CRH is its domestic-substitute line against Vishay CRCW2512-HP and ROHM SFR. In the 2512 5.1K 2W slot, lead-time and pricing beat the globals — why it shows up routinely in Chinese power-supply, industrial, and BMS BOMs.
For prototyping or volume: Shenzhen Shunhai Technology Co., Ltd. (Ever Ohms authorized distributor) carries CRH series stock; Huanian Mall (华年商城) lists CRH2512F5K10E04Z on-hand for small-lot trial runs and urgent fills.
