SWRH1004C-101MT Inductor Sourcing Review with Gujing GCDB104MT101

Gujing GCDB104MT101 is a 100 µH candidate for projects reviewing Sunlord SWRH1004C-101MT. It has the same listed 4 mm height and a closely sized external envelope. For procurement, this is an opportunity to discuss an additional source with engineering support, beginning with a complete electrical and mechanical specification.

Our application records describe sample and system evaluations for appliance-control and medical equipment. We can review your load and board requirements, discuss the technical information needed for approval and prepare a sample and quotation request around that agreed brief.

GCDB104MT101 vs. SWRH1004C-101MT: 100 µH Specification Comparison

Comparison figures are from Gujing’s technical proposal. Confirm the current approved specifications and test conditions when agreeing sample acceptance.

Discuss this pairing with our team and request the proposed specification, sample arrangements and a quotation.

Evaluating Thermal Current, Saturation Requirements and DCR

The comparison lists 10.5 × 10.5 × 4 mm for Gujing and 10.6 × 10.5 × 4 mm for the reference, with 100 µH ±20% for both. It lists a current value of 1.35 A for Gujing and 1.25 A for the reference at a stated 40 K temperature rise. These figures help start the size and thermal discussion.

The thermal-current value should not be used as a saturation limit. Include the required inductance at peak current in the technical inquiry so that saturation behavior becomes part of the proposed approval specification. DCR also needs a consistent comparison: Gujing is listed at 314 mΩ, while the reference is 304 mΩ maximum. Confirm the applicable limits before assessing winding loss or accepting a quote for production use.

GCDB104MT101 Application Records: Appliance-Control and Medical Equipment

In December 2021, a Nanjing appliance-control customer approached Gujing during component selection for SWRH1004C-101MT. We recommended GCDB104MT101 and supplied samples. The record places the project in complete-system testing, with no problem reported at that stage. It does not record final production approval.

In March 2022, a Shanghai customer requested this reference pairing for a defibrillator-related project. Our team matched the Gujing specification, the customer reviewed it and samples were provided. The record describes encouraging initial testing while further customer validation remained outstanding. These stages matter to purchasing: sample review, system verification and production release are separate milestones, especially where the finished equipment has its own qualification requirements.

Specification Review, Sample Testing and Production Approval

Selection and specification review

Before the approval test, define the required saturation behavior as well as the thermal limit. Include the maximum peak current, acceptable inductance change and ambient conditions so the candidate can be evaluated against a complete requirement.

Samples and application feedback

Discuss sample quantities and the tests needed for your circuit. Share measured temperature rise, electrical results or application issues with our technical team so we can review the candidate and, where appropriate, discuss material or design adjustments.

Trial production and order confirmation

Before production release, agree the specification, drawing and approved sample with your team. Confirm packaging, inspection requirements, order quantity and delivery schedule in the commercial discussion. A second-source evaluation can then progress through your own approval process.

SWRH1004C-101MT Candidate Evaluation: Frequently Asked Questions

Can I use 1.35 A as the saturation rating?

No. The comparison identifies that figure at a stated 40 K temperature rise. Saturation requires a separate inductance-versus-current specification and acceptance criterion.

Do the existing cases show that this pairing is already approved for my application?

They describe historical projects at sample or system-test stages. Your engineering team needs its own acceptance results and any required equipment-level qualification before production release.

Can I compare 314 mΩ directly with 304 mΩ maximum?

The figures are not described on the same limit basis. Request the applicable typical and maximum limits and measurement conditions so the comparison supports a meaningful loss and temperature assessment.

How are sample cost, MOQ and delivery confirmed?

They are confirmed for the agreed specification, sample or order quantity and packaging requirements. Include your target delivery date when requesting a quotation; historical case schedules are not current order commitments.

Request GCDB104MT101 Samples and a Quotation

Send the SWRH1004C-101MT datasheet, PCB footprint, required inductance at peak current, thermal limits, operating frequency and any equipment qualification requirements. Add expected volume and delivery timing. We can review the candidate specification and discuss the technical data, samples and quotation needed to progress the sourcing evaluation.
