Customer Stories

In April, a customer urgently needed a custom inductor. Given the long lead time and the potential wait, I initially considered declining the offer. However, the customer continued to communicate, expressing their strong interest in our products and eagerness to collaborate. To uphold their trust, I discussed the application scenarios and requirements with them the next day, collaborating on joint R&D. Initial R&D efforts were hampered by material shortages. My purchasing team and I searched over ten suppliers, narrowing down our focus to two after over a month. Once the materials arrived, we quickly produced samples for the customer to test. After two months of dedicated work, we successfully delivered the samples.
In June, the customer received a gratifying order from Russia! We not only helped them restart their project, but also earned their trust with efficient delivery and cost reduction, securing a 5,000 yuan trial production order. The customer praised us, saying, "It's rare to find such a dedicated supplier. Their dedication to new products and generous sample provision are truly touching!"
Customer satisfaction is our greatest happiness. Providing exceptional service through creative work and growing alongside our customers is our eternal pursuit.

Who We Are

Engineering Case: Technical Research on Buck-Boost Inductors and Customer Demand Response Practice

Project Background and Challenges

Customer Requirements

A smart sprayer manufacturer (project code YQ0017) required a custom high-frequency inductor component that met the technical specifications of dual inductances of 30μH/600μH and current loads of 0.3A/1.5A for use in a buck-boost circuit module.

The initial proposal (CD0805-25/800μH) was rejected due to overheating and insufficient current draw, and a 3% defect rate occurred during the pilot production phase (due to external forces causing copper wire shorts).

Technical Difficulties

1. Size constraints; how to balance inductance accuracy and heat dissipation performance within a miniaturized design.

2. Improved copper wire resistance to mechanical damage and stability.

Problem analysis and solution path

Phase 1: Parameter Optimization (September-November 2024)
Root Cause Analysis: The original inductor core material was unstable, and its saturation characteristics were not suitable for high-frequency operating conditions.
Solution Iteration: Adjusting the winding process increased the inductance of pins 1-2 from 25μH to 30μH.
Using a layered winding method to reduce eddy current losses in pins 1-3, increasing current carrying capacity by 15%.
Phase 2: Reliability Upgrade (January 2025)
Innovative Design:
Developing a new YPRH0704C-300M:601M structure, using a shielding cover + epoxy resin potting + dual protection to address copper wire wear.

Key Achievements and Benefits

1. Technical Targets Achieved Target: Industry Standard Project Outcome Defect Rate: ≤1% Response Speed: 7 days 72 hours Customer Repurchase Rate: 11 additional orders Business Value 1.
