Smoke alarm detection circuit

The TDK Group has launched a new series of transponder coils with a high sensitivity for passive passive entry systems (PEPS) and other access control systems. Among them, the B82453C*A* series 3D transponder transponder coils are extremely compact, measuring only 11.5mmx12.5mmx3.6mm, with 6 different models, with sensitivity ranging from 45mV/μT to 83mV/μT, and inductance values ​​ranging from 4.75mH to 13.2mH. . The transponder transponder coil has a center frequency of 125 kHz. The core geometry of the new 3D transponder transponder coils is optimized to make the sensitivity about 20% higher than that of previous-generation transponder transponder coils with similar geometries and inductance values ​​or competitive products of the same type. This can significantly extend the effective effective distance of the wake-up function of the onboard PEPS system.

TDK Group's CeraLinkTM series capacitors have two new Thin-Wide (LP) products with a rated voltage of 900 VDC. Both models are SMT capacitors, capacitance is 0.25μF, and supports different connection types, of which B58031I9254M062 type with L-shaped terminals, size is 10.84x7.85x4mm; and B58031U9254M062 type
