1. **Fuse Material Differences:** - **PW9603 (SMD Fuse):** - Advantages: Compact design suitable for limited spaces, especially in microcircuits and high-density circuits. Provides rapid disconnection for relatively quick protection in case of faults. However, inconvenient for replacement due to the surface-mount design. - **Competitor (Fuse Link inside a Fuse Holder):** - Disadvantages: Longer response time due to the characteristics of internal fuse elements, which may pose a risk of damaging the equipment. Larger in size, occupying more space. Advantages include ease of replacement when damaged.
2. **Differences in Surge and ESD Protection:** - **PW9603 (Your Product):** - Utilizes surge and ESD protection with ±8KV surge (differential) and ±8KV (contact), ±15KV (air) ESD capabilities. - **Competitor (Peer's Product):** - Appears to have surge protection at ±6KV and ±8KV (contact), ±8KV (air) for ESD.
3. **DC Interface Differences:** - **PW9603:** - DC input with a PE (Protective Earth) grounding terminal enhances device safety by connecting to the ground, preventing the equipment's casing from being charged and reducing the risk of electric shock. The grounding connection also reduces the device's sensitivity to external electromagnetic interference, enhancing stability and reliability. Compliance with electrical safety regulations is achieved, but the inclusion of PE grounding increases product design and manufacturing costs. - **Competitor (Peer's Product):** - DC input lacks a dedicated PE grounding terminal and relies on the casing for grounding, increasing the risk of a charged casing and potential electric shock. Non-compliance with specific electrical safety regulations. The absence of a PE grounding terminal may make the device more susceptible to external electromagnetic interference, affecting device performance.
