CRH2512F0R00E04Z 2512 0R 2W EVER OHMS Jumper Resistor Specification

1. Part Number Decoding

CRH2512F0R00E04Z is a zero-ohm jumper device from EVER OHMS' CRH high-power thick-film chip resistor series. The complete part number breaks down as follows:

• CRH: Series code for Thick Film High Power Chip Resistor. Compared with the standard CR series, the CRH line doubles the power rating within the same package footprint.
• 2512: EIA standard package size, measuring 6.30mm × 3.20mm × 0.65mm — one of the most widely used footprints for high-power SMD resistors.
• F: Tolerance grade (±1%). For 0Ω jumper products, this field denotes process consistency; actual jumper resistance is controlled at the milliohm level.
• 0R00: Nominal resistance of 0 ohms, functionally equivalent to a PCB jumper or wire bridge.
• E04Z: Suffix covering TCR grade (±100ppm/℃) and tape-and-reel packaging (4000 pieces per reel, paper tape).

2. Product Features

This 2512 0R 2W jumper resistor employs thick-film screen-printing technology on a 96% alumina ceramic substrate, with nickel barrier and pure tin terminations for solderability and long-term reliability. Key electrical specifications:

表格

Although labeled zero-ohm, the 2512 0R 2W jumper resistor exhibits milliohm-level contact and body resistance. EVER OHMS specifies a maximum post-test resistance of 20mΩ — tighter than the industry-typical 50mΩ ceiling — reflecting superior paste formulation and sintering process control in the CRH series.

Per the derating curve, when ambient temperature exceeds 70℃, rated power must be derated linearly, reaching zero at 155℃. Designers selecting the 2512 0R 2W jumper resistor for high-temperature enclosures or sealed power modules should reserve derating margin based on actual operating conditions.

3. Applications

The 2512 0R 2W jumper resistor serves three core circuit functions: bridging, configuration selection, and PCB trace routing. Typical applications include:

• Power Modules & DC-DC Converters: Jumper configuration at input/output stages and zero-ohm connection points in feedback networks. The 2W power headroom accommodates substantial transient currents.
• Home Appliance Control Boards: Hardware version switching for air conditioners, refrigerators, and washing machines — populating or omitting the device enables feature differentiation across regional SKUs.
• Industrial Control & Instrumentation: Signal bridging and ground-plane connections in PLC modules, inverters, and measurement instruments. Thick-film anti-sulfuration properties withstand harsh industrial environments.
• Automotive Electronics: Circuit jumpers in infotainment systems and body control modules (BCM). The -55℃ to +155℃ range meets automotive temperature requirements.
• Consumer Electronics: PCB layer-to-layer bridging in set-top boxes, audio equipment, and networking devices — replacing manual flying wires and improving automated assembly throughput.

4. Key Advantages

Double Power Density. A standard 2512 thick-film resistor typically carries a 1W rating; the CRH2512 reaches 2W, allowing higher continuous current within the same PCB area. At the maximum 20mΩ resistance, 2W corresponds to approximately 10A continuous current — far exceeding conventional 1W jumpers.

Tight Resistance Consistency. EVER OHMS caps jumper resistance at 20mΩ, minimizing extra voltage drop and heat generation in high-current paths and improving system efficiency.

High-Reliability Terminations. The nickel barrier prevents tin migration into the ceramic body, while the pure tin outer layer is compatible with lead-free reflow (260℃/30s), delivering superior solder yield and long-term peel resistance.

Environmental Compliance. The entire series meets RoHS 2.0 (exemption 7C-1) and REACH requirements, with lead-free and halogen-free construction — ready for EU and North American markets without additional environmental assessment.

5. Market Positioning

CRH2512F0R00E04Z targets the mid-to-high-end high-power jumper segment, serving electronics manufacturers with explicit requirements for power headroom, resistance consistency, and long-term reliability. Within the 2512 0R 2W jumper resistor category, EVER OHMS' CRH series competes directly with Yageo's RC-H and ROHM's PMR lines, differentiating through stable lead times, competitive pricing, and complete series coverage.

Standard packaging is 4000 pieces per reel in tape-and-reel format, compatible with fully automated SMT lines. MOQ is flexible, supporting both high-volume production and R&D sample quantities.
