High-quality bobbins and mounts for magnetic components

Lodestone Pacific is a global leader in mounts and bobbins, offering a range of high quality and reliable parts to streamline magnetic component design and production.

Lodestone Pacific’s wide portfolio of thermoset and thermoplastic parts and accessories includes toroid mounts, headers and bobbins for through hole and surface mount applications.


Toroid mounts and headers

Lodestone Pacific offer world leading plastic molded toroid mounts and component headers, offering over 300 difference styles and configurations. This range is designed to simplify assembly while mechanically strengthening the final component.

Their bobbins can made from either thermoset materials, for their environmental stability and ability to tolerate over 750° F without melting, or thermoplastic materials, which do not tolerate working temperatures above 500° F however are less expensive to mould.

  • Sizes: 3,3 – 56mm
  • Mountings: surface mount and through hole
  • Thermoset materials available: Phenolic and Diallyl Phthalate
  • Thermoplastic materials available: Glass Filled Nylon, Polyethylene, Poly Butylene, Polyphenylene, Liquid Crystal
  • Core shapes: EE Core, EF Core, EI (English and metric), EER, ETD, UU, UI, PQ, EFD, EP, ER, RM



 

Bobbins

Lodestone Pacific has a wide variety of RoHS, REACH, and VDE compliant bobbins for through hole and surface mount applications. Their bobbins are high quality, made from UL traceable materials.

This range of bobbins is designed to improve accuracy and speed of windings for components which need to be wound quickly and to offer specific properties. To get your products to market quicker Lodestone Pacific offer over 500 different types of bobbins in a comprehensive range of core shapes and sizes.

  • Sizes: 12,5 – 70 mm
  • Mountings: surface mount and through hole
  • Thermoset materials available: Phenolic and Diallyl Phthalate
  • Thermoplastic materials available: Glass Filled Nylon, Polyethylene, Poly Butylene, Polyphenylene, Liquid Crystal
  • Core shapes: EE Core, EF Core, EI (English and metric), EER, ETD, UU, UI, PQ, EFD, EP, ER, RM



 

 

Application notes

Application note - "Effective Mounting of Toroidal Magnetics Requires Packaging & Production Considerations"

Richard Barden, Lodestone Pacific


Today’s magnetic components are being mounted and packaged to improve durability in transit, to speed inspection time by allowing plug in testing, and to reduce production and rework costs. Read this paper and learn more about the effects of packaging and production on the design of a toroidal core.

Application note - "Transformer Bobbin & Core Selection Involves Interdisciplinary Design &Cost Issues”

Joe Casmero & Richard Barden, Lodestone Pacific


At the heart of a transformer is a bobbin or coil former supporting the winding, aligning the cores, channelling the winding and providing a termination and connection method. Read this paper and learn more about how your bobbin choice can affect your end component design.
