The CRE2512-FZ-R006E-2 from Bourns is a high-power metal-strip current-sense chip resistor from the CRE2512 family. Its ordering code specifies 6mΩ resistance (R006), ±1% tolerance (F), ±50ppm/°C TCR (Z), and a 2W power rating (-2).
The resistor uses a Mn/Cu metal-alloy resistive element, providing stable low-resistance performance for high-current sensing. Bourns specifies less than 5nH inductance and less than 3µV/°C thermal EMF, helping reduce parasitic and thermoelectric errors in precision current-measurement circuits.
The exact 2W version is rated for 2W at 70°C. Above 70°C, allowable power is derated according to the manufacturer’s derating curve and reaches zero at 170°C. The specified operating-temperature range is -55°C to +170°C.
Bourns defines maximum working current as √(P/R). Based on 2W and 0.006Ω, the theoretical maximum working current for this exact part is approximately 18.3A, subject to PCB layout, thermal conditions and applicable power derating.
The CRE2512 series covers resistance values from 1mΩ to 9mΩ with insulation resistance greater than 100MΩ. Bourns’ official product-change documentation specifically identifies CRE2512-FZ-R006E-2 as a 6mΩ, 1%, 2W, ±50ppm/°C metal-strip resistor.
For R005 through R009 values, including this R006 device, package dimensions are approximately 6.40 ±0.20mm × 3.20 ±0.20mm × 0.90 ±0.20mm. The construction drawing shows a metal-alloy plate with Ni/Sn-plated terminations.
The CRE2512 series is AEC-Q200 compliant, RoHS compliant and rated MSL 1. Bourns lists typical applications including power supplies, stepper-motor drives, battery packs, white goods and input amplifiers.
The E packaging code specifies 4000 pieces on a 180mm (7-inch) reel. Bourns currently continues to list the CRE2512 family on its official metal-strip resistor product page.
