EE 20:30 Transformer Ferrite Core With 6+6 12Pin Bobbin

An EE30 Transformer Ferrite Core with a 6+6 (12-pin) bobbin is commonly used in switch-mode power supplies (SMPS), LED drivers, and other high-frequency applications. Here’s a breakdown of the key components and specifications you might be looking for:

1. EE30 Ferrite Core Overview

• Core Type: EE (E-E type)
• Size: EE30 (center leg width approx. 10 mm)
• Material: Typically made from ferrite material (like N87, 3C90, etc.) suitable for high-frequency applications.
• Applications: SMPS transformers, flyback/forward converters, lighting ballasts, power adapters.

2. Core Dimensions (approximate)

.3. Bobbin / Coil Former Details

• Pins: 12 pins (6 on each side) – referred to as 6+6
• Mounting Type: Through-hole (THT)
• Material: Flame-retardant plastic (typically PBT or nylon, UL94V-0)
• Pin Pitch: Usually 2.5 mm or 5 mm depending on design
• Winding Window: Large enough to support multiple windings (primary, secondary, auxiliary)

4. Electrical Parameters (Variable Based on Application)

5. Common Configurations

• 6+6 pin winding:
  • Primary winding on one side (pins 1–6)
  • Secondary + auxiliary winding on the other side (pins 7–12)
  • Can support center-tapped or multiple outputs
• Mounting:
  • Usually vertical mounting with pins soldered to PCB
  • Sometimes secured with clips or glue

6. Typical Applications

• Flyback converters
• Forward converters
• Buck-boost topologies
• LED drivers
• Offline AC-DC power supplies
