• Saturation current: 1.1 A
• DC resistance: 220mOhm maximum
• Core type: Ferrite shielded drum core wirewound
• Physical dimensions: 10.00mm x 10.00mm footprint with 4.10mm maximum seated height
• Operating temperature: -40°C to 125°C
• Compliance: ROHS3 compliant, REACH unaffected
• Moisture sensitivity: MSL 1 (unlimited)
• Mounting: Surface mount, tape and reel packaging

Both components are manufactured by Bourns Inc. and maintain identical electrical performance specifications within the defined tolerance bands.

Parameter Comparison

Engineering Selection Recommendations

Both the PM104SH-101-RC and SRU1038-101Y are active production components from Bourns Inc. with full ROHS3 compliance and REACH unaffected status. Selection between these parts may be based on inventory availability, supply chain considerations, or design documentation requirements. The SRU1038-101Y maintains higher inventory levels (22,200 pcs) compared to the PM104SH-101-RC (1,082 pcs), which may influence procurement decisions for high-volume applications. Both components satisfy identical electrical and mechanical requirements for surface mount inductor applications within the specified parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can the SRU1038-101Y be used as a direct replacement for the PM104SH-101-RC?

A: Yes. Both components share identical electrical specifications (100 µH inductance, 1.3 A rating, 220mOhm DCR), core material (ferrite shielded), physical dimensions (10.00mm x 10.00mm x 4.10mm), and compliance certifications (ROHS3, REACH unaffected). They are functionally equivalent for circuit applications.

Q: Are there any differences in the inductance frequency test parameters?

A: The PM104SH-101-RC specifies inductance frequency testing at 796 kHz, while the SRU1038-101Y specifies 100 kHz. Both components maintain the same Q factor of 24 at 796 kHz and identical self-resonant frequency of 6MHz. This difference reflects measurement methodology only and does not affect component performance.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both the PM104SH-101-RC and SRU1038-101Y carry MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture precautions are required during storage or handling.

Q: What is the saturation current specification?

A: Both components have a saturation current (Isat) of 1.1 A, which is below the maximum continuous current rating of 1.3 A. This parameter defines the point at which the inductor's inductance begins to degrade due to core saturation.

Q: Are both parts available in tape and reel packaging?

A: Yes. Both the PM104SH-101-RC and SRU1038-101Y are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
