NUF2116MNT1G

NUF2116MNT1G Description

The NUF2116MNT1G from onsemi is a compact, surface-mount 2nd-order low-pass RC (Pi) filter designed for EMI/RFI suppression in sensitive electronic circuits. With a cutoff frequency of 55MHz, it effectively attenuates high-frequency noise while maintaining signal integrity. The device integrates two channels, each featuring a 64Ω resistor and 50pF capacitor, providing balanced filtering performance. Its ultra-small 2.00mm x 2.00mm footprint and 1.00mm height make it ideal for space-constrained designs. Although marked as obsolete, it remains a reliable choice for legacy or low-volume applications requiring robust noise mitigation.

NUF2116MNT1G Features

• 2nd-Order Low-Pass Filter: Delivers sharper roll-off for superior high-frequency noise rejection.
• Dual-Channel Design: Two independent 64Ω/50pF RC networks for multi-line filtering.
• Miniaturized SMD Package: 2.00mm x 2.00mm form factor suits high-density PCBs.
• ESD Protection: Enhances durability in electrostatic-prone environments.
• 55MHz Cutoff: Optimized for audio and mid-frequency signal conditioning.
• REACH Compliant: Meets environmental regulations despite obsolete status.
• MSL 1 (Unlimited): No baking required prior to reflow soldering.

NUF2116MNT1G Applications

• Audio Systems: Suppresses RFI in amplifiers, DACs, and analog audio lines.
• Consumer Electronics: Filters noise in portable devices, wearables, and IoT modules.
• Telecommunications: Protects signal integrity in baseband circuits and data interfaces.
• Legacy Equipment: Cost-effective replacement for obsolete EMI filters in industrial controls.

Conclusion of NUF2116MNT1G

The NUF2116MNT1G excels in noise-sensitive audio and signal-chain applications, offering a balance of compact size, dual-channel filtering, and ESD robustness. While discontinued, its 55MHz cutoff and Pi-network topology provide a proven solution for EMI mitigation. Engineers seeking alternatives should consider newer onsemi RC networks, but this model remains viable for repairs or niche designs prioritizing space efficiency and reliability.
