Case Study: Vietnamese Consumer Electronics Factory Scales Production with BONENS 3362 High-Volume Standard Trimmer

Client Profile: A rapidly growing Vietnamese consumer electronics contract manufacturer producing Bluetooth speakers, smart home devices, and USB chargers for global brands, with annual production exceeding 2.5 million units.

Challenge

The client's multi-product manufacturing operation required a standardized single-turn trimmer potentiometer suitable for diverse applications — audio level adjustment in Bluetooth speakers, voltage trim in USB charger circuits, and sensitivity calibration in smart home sensors. With production volumes scaling rapidly, component supply consistency and competitive pricing were critical. The previous trimmer supplier — a Southeast Asian distributor of a Japanese brand — struggled to maintain stock levels matching the client's growth trajectory, resulting in three production line stoppages over six months.

BONENS Solution

Sichuan Qixing proposed the BONENS 3362 series single-turn cermet trimmer potentiometer as the standardized trimmer solution. The 3362's industry-standard footprint and comprehensive resistance range (10Ω to 5MΩ) allowed a single component SKU strategy across multiple product lines, simplifying purchasing and inventory management. Direct manufacturer relationship with Sichuan Qixing eliminated distributor stock availability issues. Initial qualification order of 10,000 units passed electrical and mechanical testing with 99.7% acceptance rate.

Results

Standardizing on BONENS 3362 eliminated production line stoppages, reduced trimmer component SKUs from 7 to 1, and delivered 31% per-unit cost savings on annual volume of 900,000+ units. The simplified supply chain and consistent quality enabled the client to confidently scale production to meet growing brand customer demand.
