概述

Description

SRP7028A-1R0M is a surface‑mount shunt resistor (current‑sense resistor) in the SRP7028A family.
- Value and tolerance: nominal resistance 1.0 Ω (1R0) with tolerance M (±20%).
- Package: 7.0 × 2.8 mm SMD (7028 style), designed for higher current sensing with low voltage drop.
- Use: placed in DC power paths to sense load current for regulation, overload protection, and monitoring in power supplies, DC‑DC converters, motor drives, etc.
- Notes: It’s a low‑ohmic resistor meant to minimize circuit disturbance; actual power rating, temperature coefficient, and maximum current vary by manufacturer—check the specific datasheet for exact ratings and limits.

Features

I don’t have the exact datasheet for SRP7028A-1R0M. It appears to be an SMD power resistor in a 7028 package (7.0 × 2.8 mm) with 1.0 Ω resistance and M tolerance (±20%). Likely features:
- Resistance: 1.0 Ω
- Tolerance: ±20% (M)
- Package: 7028 (7.0 × 2.8 mm)
- Power rating: typically around 2 W (could vary by vendor)
- Termination: tin/lead-free plated
- Temperature range: roughly -55 to +155 °C
- Construction: thick-film or metal oxide; rugged, suitable for high current
- Compliance: RoHS
For exact specs (power rating, voltage rating, precise temp range, construction), please provide the manufacturer or a datasheet link.

Package

Package type isn’t fixed by the part number alone. Please share the manufacturer or a datasheet. SRP7028A-1R0M is typically a low‑ohm SMD shunt resistor in a 2‑pin package, but exact dimensions vary by vendor.

Pinout

Pin count: 2 pins.
Function: A 1.0 Ω shunt (current-sense) resistor used in series with a load to measure current in power-management circuits.

Manufacturer

I can’t reliably identify the manufacturer from the part number SRP7028A-1R0M alone. The code looks like a surface-mount resistor (1R0 = 1 Ω) in a 7.0 × 2.8 mm package, used by several makers. Please share a datasheet link or a supplier page (or an image) and I’ll confirm the exact manufacturer and describe the company (e.g., its primary business, whether it’s a dedicated resistor maker or a broader electronics components supplier).

Application

SRP7028A-1R0M is a low-ohm power shunt resistor. Typical application areas:
- Current sensing in switching power supplies (DC-DC, inverters)
- Motor drives and traction systems
- Automotive power electronics (BMS, DC-DC converters)
- Energy metering and power monitoring for renewable systems
- Battery packs and telecom equipment current measurement
