Why EPCOS B82498B3391J000 Stands Out in Power Management
In the realm of compact power inductors, the EPCOS B82498B3391J000 has become a go-to component for engineers designing energy-efficient systems. With an inductance of 390µH (±20%) and a current rating up to 1.2A, this shielded SMD inductor operates efficiently across a -55°C to +150°C temperature range – a critical feature for automotive and industrial applications.
Real-World Application: EV Charging Systems
A leading electric vehicle manufacturer recently integrated this inductor into their onboard DC-DC converters. The results showed:
- 15% reduction in power loss compared to previous models
- 93% efficiency maintained under 40°C ambient temperatures
- Zero failure instances after 2,000-hour stress testing
Technical Advantages That Matter
The B82498B3391J000’s iron core design delivers:
| Core Material | Iron Powder |
| SRF | >10MHz |
| Q Factor | 35 @ 1MHz |
These specs make it ideal for switch-mode power supplies (SMPS) in medical equipment where space constraints and EMI suppression are critical.
Cost-Effective Reliability
While pricing varies by quantity, bulk orders (1,000+ units) typically see 18-22% cost reductions compared to similar TDK inductors. With a MTBF rating exceeding 1 million hours, it’s become a favorite for IoT device manufacturers needing durable components for field deployments.
