RH35 Ferrite Bead Automatic Insertion High Frequency EMI Suppression for PC Boards and Semiconductor Protection

RH35 Ferrite Bead for Automatic Insertion into PC Boards

The RH35 ferrite bead is specifically designed for automatic insertion on PC boards. It uses a leaded structure and nickel-zinc (NiZn) ferrite core, providing excellent high-frequency EMI suppression across a wide frequency range. The product effectively prevents unwanted signal feedback and parasitic oscillation. It suppresses voltage and current spikes in circuits, offering reliable protection for semiconductor devices. Multiple models are available to meet different interference suppression requirements. Soldering methods support both wave soldering and reflow soldering. Terminal bending strength is ≥24.5N. It is widely used in PC board EMI suppression, power filtering, signal line noise suppression, and various semiconductor protection circuits.

FAQ

Q: What are the characteristics of nickel-zinc (NiZn) ferrite cores?

A: Nickel-zinc ferrite offers high resistivity and excellent broadband characteristics. It provides low core loss at high frequencies, suitable for EMI suppression applications from MHz to GHz bands. Compared to manganese-zinc ferrite, NiZn material is more suitable for high-frequency interference suppression.

Q: How does the leaded ferrite bead achieve automatic insertion?

A: The RH35 series uses standardised pin spacing and lead dimensions. It is compatible with automatic insertion machines (automatic vertical/horizontal component inserters), enabling high-speed automated production and improving PC board assembly efficiency.

Q: How does this product suppress voltage and current spikes?

A: The ferrite bead presents high impedance at high frequencies, converting high-frequency spike energy into heat and dissipating it. This suppresses voltage and current spikes, protecting downstream semiconductor devices from transient overvoltage/overcurrent surges.
