Product Announcement
TDK Corporation has announced the expansion of its ADL3225VF series of automotive Power over Coaxial (PoC) wire-wound inductors. Mass production of these new components commenced in March 2025[1].
Key Product Specifications
- Dimensions: 3.2 × 2.5 × 2.3mm (length × width × height)
- Rated Current: Up to 1600mA (1.6A)
- Operating Temperature Range: -55°C to +155°C
- Performance Characteristics: Provides high impedance across a wide frequency spectrum (tens to hundreds of MHz)[1]
Technical Innovations
The new ADL3225VF series demonstrates significant advancements compared to previous generations:
- Achieves identical rated current (1.6A) as the larger ADL4532VK series while reducing mounting area by approximately 45%
- Delivers approximately 20% higher rated current compared to the traditional ADL3225VM-2R2M product
- Utilizes proprietary materials and innovative structural design to achieve these performance breakthroughs[1]
Application Context
These inductors are specifically designed for Advanced Driver Assistance Systems (ADAS) that utilize vehicle cameras and sensors for monitoring driving conditions. The PoC technology enables:
- Simultaneous transmission of power and data through a single coaxial cable, eliminating separate lines
- Simplified vehicular wiring architecture
- Reduced vehicle weight, resulting in improved fuel efficiency and lower carbon emissions[1]
Industry Significance
This product development carries substantial importance for the following reasons:
- Addresses the increasing complexity of electronic systems in modern vehicles
- Supports the automotive industry's pursuit of lighter, more efficient vehicles
- Facilitates more sophisticated ADAS implementation through simplified wiring[1]
Future Development
TDK has committed to continuing development of inductors for automotive PoC applications through:
- Design optimization via advanced lamination, winding, and film technologies
- Product line expansion to enhance PoC transmission signal quality[1]
This product represents TDK's ongoing innovation in passive components supporting the trends of vehicle electrification and automation.
