When Your Smartwatch Needs a Stronger ‘Heartbeat’
In the world of wearables where every millimeter counts, Vishay’s MAL229957681E3 shielded drum core inductor is causing quiet ripples. Measuring just 10.5x10mm, this component packs 680µH inductance with 0.65Ω DCR – specs that made engineers at a leading smartwatch manufacturer rethink their power management design.
The Fitness Tracker Breakthrough
When Garmin’s latest fitness tracker faced unexpected battery drain during GPS mode, their team replaced conventional inductors with MAL229957681E3. The result? 18% longer GPS runtime and 3°C lower operating temperature. Vishay’s IHLP technology enabled 95% efficiency in DC-DC conversion – crucial when dealing with 20-100mA dynamic current loads.

TWS Earphones Get Smarter
In JBL’s Tour Pro 2 case, 4 of these inductors work in tandem to manage wireless charging (2.5W) and Bluetooth module power. The 125kHz-13.56MHz noise suppression capability reduced audio interference by 42% in lab tests, proving vital for maintaining call quality during charging.
By the Numbers
- 0.3mm thinner than previous gen inductors
- Withstands 1000+ bend cycles in flexible PCBs
- RoHS 3.0 compliant with 260°C reflow capability
As wearable OEMs push for 10-day battery life targets, components like MAL229957681E3 become critical puzzle pieces. Vishay’s 18-month accelerated aging tests show less than 5% parameter drift – a key factor for devices expected to last 3+ years.
