Description and Introduction

Multilayer Chip Inductors The part **LL2012-FR39J** is a **ferrite bead** or **chip inductor** designed for noise suppression in electronic circuits. Here are its key specifications, descriptions, and features:

### **Manufacturer Specifications:**
- **Manufacturer:** Likely from a major passive component supplier (e.g., Murata, TDK, or Taiyo Yuden, though exact brand not specified in the provided data).
- **Package/Size:** **2012 (0805 metric)** – Standard surface-mount (SMD) footprint.
- **Inductance:** **39 µH (microhenries)** – Indicates its impedance characteristics for filtering noise.
- **DC Resistance (DCR):** Typically low (exact value depends on manufacturer datasheet).
- **Rated Current:** Varies by manufacturer but generally in the range of **a few hundred milliamps**.
- **Tolerance:** Usually ±25% for ferrite beads unless otherwise specified.
- **Operating Temperature Range:** Typically **-40°C to +125°C** (confirm with datasheet).

### **Descriptions:**
- **Function:** Acts as a **high-frequency noise suppressor** by attenuating unwanted EMI/RFI signals.
- **Material:** Ferrite core (nickel-zinc or manganese-zinc composition) for effective high-frequency impedance.
- **Applications:** Used in power lines, data lines, and signal paths in **consumer electronics, automotive circuits, and communication devices**.

### **Features:**
- **Impedance at Frequency:** Provides high impedance (e.g., **~600Ω at 100MHz**, exact value varies by model).
- **Compact SMD Design:** Suitable for high-density PCB layouts.
- **Non-polarized:** Can be installed in any orientation.
- **RoHS Compliance:** Lead-free and meets environmental standards.

For precise electrical characteristics (e.g., current rating, impedance curve), refer to the manufacturer’s datasheet for **LL2012-FR39J**.
