Product Description
High Voltage EEL16 Multi-slot Step-up Transformer High Frequency 12V 24V to 200V 500V Transformer for Ozone Generator
Product Overview
The EEL16 Multi-slot Transformer is a high-precision magnetic component designed for low-power Switch Mode Power Supplies (SMPS) typically ranging from 5W to 12W. The "EEL" designation represents an extended (longer) version of the standard EE16 bobbin, providing more winding room and vertical clearance. The "Multi-slot" feature utilizes a partitioned bobbin to physically separate winding sections. This makes the EEL16 an ideal choice for smart home devices, IoT sensors, and auxiliary power modules where safety insulation and compact footprints are top priorities.

Key Features
- Multi-Section Slotted Bobbin: The bobbin is divided into 2 to 4 physical slots, allowing for the segmented winding of primary and secondary stages.
- Extended EEL Core Geometry: The elongated core provides a superior "Surface Area-to-Volume" ratio, aiding in thermal dissipation despite its miniature size.
- Broad Frequency Support: Optimized for switching frequencies between 50kHz and 200kHz, ensuring compatibility with high-efficiency green-mode PWM controllers.
- High-Permeability Ferrite: Utilizes premium PC40 or PC44 Mn-Zn ferrite materials to maintain low core losses and high saturation flux density.
Technical Insights
How does the multi-slot bobbin of the EEL16 enhance creepage distance in compact IoT power modules?
In miniature modules like IoT sensors, PCB space is extremely limited. A standard EE16 bobbin relies on multiple layers of insulation tape to separate the primary and secondary windings, which can be inconsistent. The EEL16 multi-slot bobbin introduces integral physical walls (partitions) that guarantee a fixed creepage distance. By winding the primary in one slot and the secondary in another, the transformer achieves a high safety margin (up to 4.0kV isolation) that meets international safety standards like IEC 62368-1 without requiring expensive triple-insulated wire (TIW).

What impact does the multi-section winding approach have on the EEL16's EMI performance and parasitic capacitance?
The multi-slot structure significantly reduces Inter-winding Capacitance (𝐶𝑝). By placing the primary and secondary windings in separate physical sections rather than layering them directly on top of each other, the overlapping surface area is minimized. Lower 𝐶𝑝 reduces the transfer of Common-Mode Noise from the primary switching circuit to the secondary output. For the design engineer, this results in a much cleaner EMI profile, often simplifying the input filter design and reducing the cost of the final product's EMC compliance.

Applications
- Smart Home & IoT: Powers small connected devices such as smart plugs, light switches, and security cameras.
- Industrial Sensors: Provides isolated power for precision transducers and measurement modules in automated factories.
- Small Domestic Appliances: Used in coffee machines, rice cookers, and humidifiers for stable auxiliary control power.
- Smart Meters: Ideal for energy meters requiring high surge resistance and long-term durability in a vertical form factor.
Product Advantages
- Enhanced Safety Design: The physical partitions simplify the design process for achieving reinforced insulation and high dielectric strength.
- Low Distributed Capacitance: SEG-winding inherently improves electromagnetic compatibility, making it easier to pass strict EMI tests.
- Space-Efficient Vertical Profile: The slim, extended vertical design allows for a high component density on the PCB, perfect for narrow enclosures.
- Excellent Manufacturing Consistency: Slotted bobbins act as a guide for automated winding equipment, ensuring that every batch has identical leakage inductance and DCR values.
