Power Bank Circuit TVS & ESD Protection

When Mobile Power is Critical, Reliability is Paramount Potential Safety Hazards in Portable Power Solutions While mobile power banks provide indispensable convenience to users, they inherently pose potential safety risks if not designed correctly. Substandard battery cells represent the primary…

CCTV USB Connector ESD Protection

1.ESD Application Solution for Single-Port USB 2.0 The operating voltage of a USB interface is typically 5V. While slight voltage fluctuations may occur, they generally do not exceed a range of ±0.2V, maintaining a level between 4.8V and 5.2V. For…

CCTV BNC Interface ESD Protection

The BNC interface of surveillance cameras is typically employed for video signal transmission. Since these video signals are analog in nature and generally characterized by low voltage levels, they require reliable protection. For the BNC interfaces of surveillance cameras, JY…

CCTV RJ45 Port ESD Protection

The architecture of a surveillance camera’s Ethernet port can be segmented into three primary components from the external interface inward, as illustrated in Figure 1: (1) RJ45 connector, (2) Transformer, and (3) LAN PHY. The section between (1) and (2)…

CCTV Power Port ESD Protection

Surveillance cameras are frequently deployed in outdoor environments, exposing them to harsh and complex electromagnetic conditions. During thunderstorms, they are particularly susceptible to lightning-induced transients. The resultant overvoltage and overcurrent from lightning surges can compromise the system’s electromagnetic compatibility (EMC)…

Smart Band RF Connector ESD Protection

The entire ESD protection ‘defense system’ of a Smart Band, from sensors to circuits, is a continuous battle against static electricity, the ‘invisible killer.’ Among these protective layers, the Radio Frequency   Connector stands as the ‘data throat’ of a Smart Band—it…
