概述

Description

SPM4030T-1R0M is a shielded surface-mount power inductor in the 4030 package (roughly 4.0 × 3.0 mm). The "1R0" typically indicates about 1.0 µH inductance, and the "M" suffix denotes ±20% tolerance. The "T" often reflects a series or temperature/rating variant, depending on the manufacturer. It’s used in DC–DC converters and VRMs to store energy and filter current ripple, with a compact, low-profile, EMI-shielded construction suitable for high-current applications. For exact specs—DC resistance, saturation/current ratings, and operating temperature range—consult the specific vendor’s datasheet, as these values can vary by producer.

Features

SPM4030T-1R0M is typically a 4.0 × 3.0 mm SMD power inductor. Exact specs depend on the manufacturer, but common features include:
- Type: Shielded surface-mount power inductor
- Size: 4.0 × 3.0 mm
- Inductance: 1.0 µH (1R0)
- Tolerance: ±20% (M)
- Core/Construction: Ferrite core, molded, shielded
- Termination: Sn-plated leads
- Temperature range: -40°C to +125°C
- RoHS compliant, reflow solderable
- Low DC resistance; suitable for power-supply circuitry
- Available in reel/tape packaging for automated assembly
Note: For exact rated current, DC resistance (DCR), saturation current, and reliablity specs, please share the manufacturer or a datasheet link.

Package

I can’t determine the package type from the part number alone. Please provide the manufacturer or a datasheet link. SPM4030T-1R0M may refer to a 4030‑size SMD package, but confirmation from the vendor is needed.

Pinout

I don’t have enough information to give pin count or function for SPM4030T-1R0M. This part number can refer to different devices across packages from various manufacturers, and pinout depends on the exact package and datasheet.
Please provide:
- Manufacturer or a link to the datasheet
- Package type (e.g., SSOP, QFN, TSSOP) or any marking on the body
With that, I can give the exact pin count and each pin’s function.

Manufacturer

- Manufacturer: Sumida Electric Co., Ltd. (Sumida)
- What kind of company: A Japanese electronics components company that specializes in magnetics, including inductors, transformers, and chokes for power supplies and other electronics.

Application

Typical applications for SPM4030T-1R0M (a high‑current, low‑Rds(on) power MOSFET module) include:
- Switch‑mode power supplies and DC‑DC converters
- Motor drives (BLDC/PMSM) and speed controllers
- Automotive power electronics
- Solar inverters and uninterruptible power supplies
- Telecom and general power‑management boards
Refer to the datasheet for exact voltage/current ratings and package details.

Equivalent

I don’t have real-time cross-reference data for SPM4030T-1R0M. Please share the datasheet or the device function (e.g., regulator, switch, driver) and key specs (voltage, current, package). I can then suggest exact equivalents from TI, Analog Devices, ST, ON Semiconductor. For quick results, use distributor cross-reference tools (Digi-Key, Mouser, Arrow) by part number and by electrical/spec parameters.
