Ensuring Continuity for a Critical RF Inductor in a U.S. Electronics Program

Customer Profile

A U.S.–based electronics manufacturer supporting high-frequency and RF-enabled products for industrial and communication applications. Their designs prioritize compact layouts, signal integrity, and long-term product stability, making component consistency critical.

The Challenge

The customer required the Bourns CI100505-6N8J multilayer inductor for an active production build.

While the part itself is small, the challenge was significant:

• The exact value and footprint were design-critical

• Alternatives risked signal degradation and re-tuning of RF paths

• Market availability was inconsistent, with unreliable listings

• Any deviation in electrical performance could impact system compliance and performance

With production timelines approaching, the customer needed a trusted source that could supply the exact component, not a near substitute.

Why the Component Is Critical

CI100505-6N8J – Bourns Multilayer Inductor

• 6.8 nH inductance

• 0402 (1005 metric) footprint

• 300 mA current rating

• Low DCR (250 mΩ max)

• Unshielded multilayer construction

This inductor is commonly used in:

• RF matching networks

• Signal conditioning circuits

• High-speed communication interfaces

• Compact industrial electronics

Even minor deviations in inductance or parasitics could compromise performance—making exact sourcing non-negotiable.

Maketronics’ Role: Precision Sourcing with Quality Assurance

Maketronics leveraged its vetted supplier ecosystem to locate:

• Exact part number CI100505-6N8J

• New, unused components, suitable for production

• Stock aligned with the customer’s quantity and timeline requirements

To ensure confidence, the parts underwent structured quality checks aligned with Maketronics’ assurance process, confirming:

• Correct markings and physical condition

• No signs of prior use, rework, or damage

• Compliance with form, fit, and functional expectations

This ensured the components were production-ready upon arrival.

Results Delivered

• The customer received the exact inductor required, without substitutions

• Production timelines remained intact

• No redesign or RF requalification was needed

• Engineering and procurement risks were minimized

Key Takeaway

In high-frequency and RF designs, small components carry big risk. Maketronics helps U.S. manufacturers secure precise, hard-to-source passives—protecting performance, timelines, and design integrity.

When component availability threatens your build, we step in with certainty.
